Built-in preset router

LingTai ships exactly four provider families, one built-in template each. This router covers exactly the names returned by BuiltinPresets() in tui/internal/preset/preset.go. It covers TUI-owned template presets only, not arbitrary saved presets. Route a named-preset question or revision to the direct child with the matching name under reference/<name>/SKILL.md. That child owns the family's endpoint/credential facts, exact TUI surfaces, and named-preset revision instructions.

There are no per-vendor templates. Any other vendor, subscription, gateway, or account pool is reached through the openai or anthropic family pointed at that vendor's compatible endpoint (base_url) — never through a vendor-named provider, which the kernel rejects.

Direct children: the 4 BuiltinPresets names

Name	Provider	Direct child	Route hint
codex	codex	reference/codex/SKILL.md	ChatGPT-account (Codex OAuth) route; the first-run default
claude	claude-code	reference/claude/SKILL.md	local Claude Code CLI login ("claude-p")
openai	openai	reference/openai/SKILL.md	any OpenAI-compatible endpoint, Chat Completions or Responses; also account pools such as sub2api / subs-pool
anthropic	anthropic	reference/anthropic/SKILL.md	any Anthropic Messages-compatible endpoint

- name: preset-skill-codex
  location: reference/codex/SKILL.md
- name: preset-skill-claude
  location: reference/claude/SKILL.md
- name: preset-skill-openai
  location: reference/openai/SKILL.md
- name: preset-skill-anthropic
  location: reference/anthropic/SKILL.md

Do not merge the Codex OAuth catalog, the Claude CLI aliases, and an arbitrary endpoint's served models. openai and anthropic have no universal model: the model is free text and must be checked against the configured endpoint. The exact constructor in preset.go is always the first source to inspect; picker, capability, and credential surfaces are listed by each direct child.

Shared operation children: five unchanged mechanics

Question	Child
Saved templates/presets, load/save/delete, and bootstrap ordering	reference/operations/saved-presets/SKILL.md
Endpoint, provider/model/capability declarations, and Codex OAuth quota	reference/operations/endpoint-capabilities/SKILL.md
Whether Save calls a provider and where availability is diagnosed	reference/operations/availability-save-gate/SKILL.md
Activation, session state, and what refresh switches	reference/operations/activation-session-refresh/SKILL.md
Bounded troubleshooting and migration routing	reference/operations/troubleshooting-migration/SKILL.md

- name: preset-skill-op-saved-presets
  location: reference/operations/saved-presets/SKILL.md
- name: preset-skill-op-endpoint-capabilities
  location: reference/operations/endpoint-capabilities/SKILL.md
- name: preset-skill-op-availability-save-gate
  location: reference/operations/availability-save-gate/SKILL.md
- name: preset-skill-op-activation-session-refresh
  location: reference/operations/activation-session-refresh/SKILL.md
- name: preset-skill-op-troubleshooting-migration
  location: reference/operations/troubleshooting-migration/SKILL.md

These five children remain shared production mechanics. A named revision composes its direct child with the mechanics it needs; it does not create a second provider tree or a revision operation child.

Deterministic revision CLI and engine

For a reviewed change, prepare an evidence-bound manifest and explicit input, then run:

lingtai-tui presets revise --manifest PATH --input PATH \
  --mode dry-run|check|apply [--output-dir PATH]

The headless adapter at tui/internal/headless/preset_revision.go reads only those paths and dispatches before preset bootstrap, provider access, OAuth, MCP, network, auth, or runtime reads. dry-run and check do not write; apply requires a new explicit output directory. The pure engine at tui/internal/preset/revision.go validates the typed target state, route bindings, evidence, expected old values, and input/post-image hashes, then splices only owned JSON bytes while preserving unowned bytes. Review the JSON plan and diagnostics before apply.

Boundaries and maintenance

Family children record only reviewed facts and official lookup paths; a failed direct route is not permission to switch providers, guess credentials, or auto-load an MCP. Saved presets may change provider, model, endpoint, credentials, or capabilities, so inspect their actual manifest. A saved preset that still names a retired vendor provider (custom, deepseek, minimax, ...) must be moved to one of the four families — see reference/operations/troubleshooting-migration/SKILL.md.

When BuiltinPresets() gains a new template name, add exactly one matching direct child and catalog row in the same PR. When a new cross-cutting mechanic is added, extend the five-operation catalog rather than adding a revision child. When a relevant TUI preset/page is revised, check the matching child and include its revision in the same PR when needed.
